# --description--

Next, you want to center the `div` horizontally. You can do this by setting its `margin-left` and `margin-right` properties to `auto`. Think of the margin as invisible space around an element. Using these two margin properties, center the `div` element within the `body` element.

# --hints--

You should set the `margin-left` property to `auto`.

```js
const hasMargin = new __helpers.CSSHelp(document).getCSSRules().some(x => x.style['margin-left'] === 'auto');
assert(hasMargin);
```

You should set the `margin-right` property to `auto`.

```js
const hasMargin = new __helpers.CSSHelp(document).getCSSRules().some(x => x.style['margin-right'] === 'auto');
assert(hasMargin);
```

You should set the `margin-left` and `margin-right` properties of your `div` to `auto`.

```js
const divMarginRight = new __helpers.CSSHelp(document).getStyle('div')?.getPropertyValue('margin-right');
const divMarginLeft = new __helpers.CSSHelp(document).getStyle('div')?.getPropertyValue('margin-left');
assert(divMarginRight === 'auto');
assert(divMarginLeft === 'auto');
```
